New data on the gravitational field of the moon // Observation and Understanding of the Moon, Moons&Planets. — 2 IAPS. — Kazan Federal University Tatarstan, 2015. — P. 89–91. New data on the gravitational field of the Moon were obtained from two Grail spacecrafts. The spacecrafts were launched on September 10, 2011 and received the names of Ebb and Flow. The probes flew on the same orbit, one after the other at a height of 55 km above the lunar surface. It can be assumed that mascons include rich KREEP rocks with a high content of thorium and iron oxide. KREEP rocks in the areas of the lunar Maria covered by volcanic lava are probably located on the surface or at a shallow depth.
